“Neurons that fire together, wire together” is not the full story. A novel mechanism explains how the brain can learn across longer timescales.

Dozens of new discoveries reveal that defenses evolved by bacteria and viruses billions of years ago still define our own innate immune system.

A vast meshwork of soil-bound fungi governs life aboveground. In Alaska, and at field sites around the world, researchers are racing to understand exactly how, with essential stores of carbon at stake.

Every second, hundreds to thousands of molecules move through thousands of nuclear pores in each of your cells. A new high-definition view reveals the machine in action.

Growing tissues can crack, break, and dissociate to form structures that can later withstand immense forces.

Innovations in imaging and genetic engineering are coming together to probe the biophysics of cytoplasm inside living animals.

Machine learning is helping neuroscientists organize vast quantities of cells’ genetic data in the latest neurobiological cartography effort.

How physically magnifying objects using a key ingredient in diapers has opened an unprecedented view of the microbial world.

New experiments reveal how astrocytes tune neuronal activity to modulate our mental and emotional states. The results suggest that neuron-only brain models, such as connectomes, leave out a crucial layer of regulation.
